Great Quality

A most have charger for your Fenix rechargeable flashlight. I found it easy to read as it provides multiple readings. It's also fast charging. I recommend this product.

Never had a problem with their chargers or batteries. In fact, I've had a battery last for 10 years and had many hours of use time

Charger and extra battery

The charger and battery together is a great value and it’s so very new c’è to have a spare battery for when you need it never right now but battery life. I think you will be by more.

Back up battery

Works like it was advertised and 20% off no complaints your flashlights are the best I’ve ever used. This is my third one.

Here's the thing. The product itself is good, but I'm not sure if info in the description is wrong or I misread it. I bought this under the impression that it was compatible with the 18650 battery since my flashlight (tk20 v1 I think) can only fit up to that. So now I'm stuck between returning this or buying another battery. The battery itself is good though and I like the info provided by the charging kit.

I guess I'm a little confused on the review. The 21700 Battery Kit includes the ARE-D1 charger, and a 21700 battery. The 21700 battery is bigger than the 18650, so it won't work in a light that uses the 18650. The ARE-D1 charger can charge both the 21700 battery, or an 18650 battery, as the slot size is adjustable. So I'm not sure if you were stating you thought the charger works with both sizes, which it does, or if you thought the 21700 battery and 18650 battery are interchangeable?
